POWER TRAVERSE AND FEEDJWECHANISIVI FOR PLANERS.

Application vfiled. March 6, 1320. Seria11 1"o.-363,765;

Be it known'that I, ALFRED TROSCH, a citizen of the United States, and resident of Rochester, county of Monroe, State of New York, have invented an Improvement in Power Traverseand Feed Mechanism for Planers, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts in each of the several views.

This invention relates to metal working planers and more particularly to an improved arrangement and disposition of power connections for operating the tool heads on the crossrail and on the side uprights whereby these may be moved rapidly for traversing .the same to or from an operative position, or operated at relatively slow rates by other connections for the feed movement thereof in the operation of the machine. A principal object of the invention is to provide a relatively simple, com-- pact, and reliable system of connections for the distribution of power whereby either the feed 01' the rapid traverse for any tool head may be instantly thrown into or out of engagement, the arrangement being such that there is no possibility of the feed and rapid'traverse being both engaged at the same time, and the controlling elements being located in convenient position for manipulation by the operator. The foregoing and other objects and advantages of the invention will more fully appear from the following detailed description, and the distinctive features of novelty will thereafter be pointed out in the appended claims.

Referring to the drawings:

Fig. 2 is a partial side view thereof with portions broken away;

indicates a planer bed on which is fitted a usual reciprocatingtable 11. 12 are the side uprights only one thereof being shown at one side of the machine, these besection on line ing joined by the usual top rail 120 to con .stitute the upright housing on which the crossrai'l ltOanCl' the tool heads are mounted for adjustments and operative movements. 13 indicates a motor-mounted oil-the" top rail 120, this motor being of a-reversil)le type or adapted through reversing" gearing to'drive a shaft 14 horizontally journa'led at the top of the housing, in either directlon. r

-.The shaft 14 through bevel gearing 15 drives a shaft. 16 which is vertically journaled to extend downward alongside ofthe upright '12. This shaft'is: formed with a keyway 16 extending through'the majorintermediate portionof the length thereof. Slidablyikeycd on the shaft: 16 is a bevel pinion 17 which drives-a bevel. pinion18 fixedon ashort shaft 19 journa'led in a bearlngbracket 20 borne by: the crossrail. The pinion 17 isha'lso' journaled in thisbrack'et so as to move vertically with the crossr'ail while being driven in all its-vertical positions by .the shaft 16.

loosely fitted thereon-a pinion 1 21 which is engaged with a'gear 22loosely'mou nted on a bearing shaft 23 born'e:byitheicrossrail. Thegearl 22 is adapted to operate thecrossrail screws 24' or the crossrailshaft 25 selectively by means ofthe click box pinions: 26 in usual manner. The shaft 19 has slidably keyed: thereon a clutch hub 27 which is adapted to engage a co-operative clutch face on the pinion '21" and upon moving-this clutch hub to thus make 'thepinion .21 fast to the shaft 19 rapid .traversemovement will be transmitted through the described connections from the motor 13 in either direc tion to a selected feed screw. or shaft of the crossrail. 28 indicates a feed boii at the base ofthe machine which maybe of usual type and actuatedfin usual manner by the table driving connections. This "feed box t irough a pitman 29-operates a segmental gear 30 journaled'in a bra'c'ket'3l at the base of the machine and having a lateral projecting arm' 30 with which the :p'itman 29 'is directly engaged. The gear segment 80 meshes with a pinion '32 fixed at't'he lower 'endiof ashaft 33 verticallyjourn aled alongside the upright. The shaft 33-has a key-' way extending the major portion of the length thereof. Toe this shaftis slidably keyed a pinion 3 1' journal'ed and heldfrom endwise movement in a bearinglug 20 of The shaft 19 has the bearing bracket 20 borne by the crossrail. The pinion 3e meshes with a pinion fixed on a short shaft journaled in the bracket 20 and having fixed at its outer end a feed plate This feed plate-is slotted radially of said shaft as indicated at 56 and in this slot is adjustably fitted a crank pin 3"? at the end of a pitman 38. The pitman 38 has its other end engaged with a lever which has a hub 59 journaled on a sleeve extension 22 of the gear Slidably keyed on the sleeve extension 22 is a clutch hub at) and the lever hub 59 is equipped with a clutch face adapted to be engaged by said clutch hub when it is moved inward, to thus make fast the lever 39 to the gear 22, When this clutch connection is made therefore, feed movement will be imparted from the feed box 28 to a selected feed screw or shaft 2a, 25. The clutch hubs 27, it), have grooved necks 527 which are engaged by pins or rolls borne by a shifter lever tl, this lever having an intermediate pivot or fulcrum 42 between these clutch hubs and having a handle ll extending downward for convenient ac- V tuation. With this intermediate fulcrum of the lever it will be understood that when one of the clutch hubs is in, the other is necessarily out, while in anintermediate po sition both clutchhubs are disengaged. For imparting rapid traverse movement to the side tool head which is mounted on the upright 12, the shaft 16 has fixed at the lower end thereof a bevel pinion 4L3 which meshes with a bevel id fixed on a short shaft a5 journaled in a lateral bracket extension re of a side tool head &6 which is fitted to slide on the upright 12. The shaft 45 has loosely mounted thereon a pinion i? equipped with a clutch face at one side thereof which is engageable by a clutch hub 48 slidably keyed on the shaft 45. The pinion 4i? meshes with a gear 4L9 mounted on a bearing shaft 50 and having a sleeve i9 extending therefrom, i Vhen the pinion 4:7 is made fast to the shaft 45 by the clutch described, rapid traverse movement will be transmitted to the gear a9 and thence to a pinion 51 fixed at one end of a shaft 52, this shaft being horizontally journaled in an extension of the side tool head 4:6 and having fixed at its inner end a spiral gear 53 which drives a vertical spiral gear 54. The gear 5% is held from endwise movement between lugs 55 of the tool head and it has a threaded passage therethrough so as to constitute a nut engaging a stationary screw 56 extending vertically in the upright 12 and fixed at its lower end in the base of-the machine as indicated at 56 Thus the rapid traverse movement as described, imparted to the nut 54 effects a raising and lowering of the tool head 46. For

' impartingfeed movement to the tool head 46 the shaft 33 has slidably keyed thereon a bevel pinion 57 which is mounted in the side head bracket 46 for movement with. The pinion 57 engages a pinion 58 fixed to a short shaft journaled in the bracket at? and having fixed at its outer end a slotted feed plate 59. This feed plate has adjustably en aged in theslot thereof a crank pin 60 at one end of a pitman 61, the other end of which engages an arm 62 which has a sleeve hub 69f loosely mounted on the sleeve extension 49 with a clutch face formed thereon. This clutch face is engageable by a clutch hub 63 slidably keyed on the sleeve til and thereby the arm 62 may be fast to the gear 49 by shifting said larly as the lever ll to engage either the rapid trav rse or the feed, or to disconnect both in an intermediate position as seen in Fig. 1. Thus either a'variable feed or rapid traverse movement may be engaged with the feed screws and rods for operating the tool heads on the crossrail, or with the side tool head, as maybe required, and the levers for controlling these connections are arranged in most convenient position for control by the operator at the side of the machine and adjacent each other. T am aware that the invent-ion may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and therefore desire the present embodiment to be considered in all respects as illustrative and not restrictive, reference being had to the appended claims rather than to the fore going description to indicate the scope of the invention.
